What pressure sensors work with 4WREE valves?
Rexroth's HM series pressure sensors (e.g., HM18-1X/250-C-K35) or third-party sensors with 4-20 mA output are compatible for pressure feedback applications.
Can I add a position feedback sensor to a 4WREE valve?
Yes, optional position feedback sensors (inductive or potentiometric) can be installed to monitor spool position and enable closed-loop control.
What is the purpose of a bypass valve with 4WREE installations?
A bypass valve allows fluid to bypass the 4WREE during maintenance or emergency shutdowns, preventing system pressure buildup.
Are there protective covers available for 4WREE valves?
Yes, Rexroth offers IP65-rated protective covers for solenoid coils and electronics to shield against dust, moisture, and mechanical damage.
Can 4WREE valves be used in mobile hydraulic applications (e.g., excavators)?
Yes, compact models (NG 6-10) are suitable for mobile equipment, provided they are protected from vibration and extreme temperatures (use shock mounts if needed).
